I notice this is consistently failing for non-power-of-two texture sizes,
but only for gnome-shell[3624], not for gnome-shell[985].
3624 appears to be running as uid 'user'- the actual login session -
whereas 985 is presumably Debian-gdm running the login prompt, which is
also done using gnome-shell.

I'm not sure what would be different for the Debian-gdm instance in terms
of driver support for "NPOT" textures, but perhaps this points someone
else in the right direction?
